NIST TREC Disks 4 and 5: Retrieval Test Collections Document Set

Data provided by  National Institute of Standards and Technology

A collection of full-text documents from various sources including the Financial Times Limited (1991, 1992, 1993, 1994), the Congressional Record of the 103rd Congress (1993), the Federal Register (1994), the Foreign Broadcast Information Service (1996), and the Los Angeles Times (1989, 1990). These documents are the document set for several TREC information retrieval test collections. (Data contains document text only.)

Data from: NIST Properties of Molten Salts Database (formerly SRD 27)

Data provided by  National Institute of Standards and Technology

NIST distributed the NIST Properties of Molten Salts Database from 1990 to 2004. As part of the NIST Standard Reference Data Program, the database was designated as Standard Reference Database 27 or SRD 27. Since the database has not been actively maintained since 1991 the SRD designation has been dropped. The database was distributed as a program for DOS compatible operating systems. To enable use of the data on modern systems, the data have been extracted into comma separated variable (CSV) files.

NIST Phase Diagrams & Computational Thermodynamics of Solders

Data provided by  National Institute of Standards and Technology

Phase Diagrams and Computational Thermodynamics - Solder Systems predicts melting temperatures and freezing ranges of lead-free solders which are used to remove lead-containing components from commercial products. This database also shows the effects of non-equilibrium solidification. Also included is a collection of calculated binary and ternary systems that are relevant to solders.

The NBS Tables of Chemical Thermodynamic Properties: Selected Values for Inorganic and C1 and C2 Organic Substances in SI Units

Data provided by  National Institute of Standards and Technology

Recommended values are provided for chemical thermodynamic properties of inorganic substances and for organic substances usually containing only one or two carbon atoms. Where available, values are given for the enthalpy of formation, Gibbs energy of formation, entropy, and heat capacity at 298.15 K (25 degrees C), the enthalpy difference between 298.15 and 0 K and the enthalpy of formation at 0 K. All values are given in SI units and are for a standard state pressure of 100 000 pascal.
